To all whom it may concern: a

Be it known that I, GUsrAv citizen of no country, and a resident of theborough of Brooklyn, county of Kings, city` and State of New York, haveinvented certain new and useful Improvements in Water- Skates, of whichthe following is a specification.

This invention relates to improvements in devices by means of which aperson may skate or glide upon the surface of a body of water. i

The invention has for its principal objects the provision of meanscontrolled by the movement of the feet of the operator for propellingthe sustaining means over the surface of the water, and to providepropelling means adjustable to permit backward movement when desired. f

There are other important yobjects and advantages of the invention, allof which will hereinafter appear.

In the accompanying drawings, Figure 1 is a plan view of the device;` 1

and 4 showing another modified construction of the device;`and Figs. 10and 11 detail views showing a modified form of impeller blade reversingmeans.

l Referring to the various parts by numerals, 1 and 2 designate a pairof long and narrow floats or buoyant hollow sustaining devices,preferably pointed at their ends as shown. Each float is provided midwayits ends with a foot plate or rest 3 and also with a hand-rail 4supported on a pairfofA standards 5. A bar 6 extends longitudinallybetween the floats 1 and 2 above the waterline and is supported at itsforward end by means of a vertically extending rod 7 rigidly HAnBow, a j

held at its lower end to said bar and provided vvith an integralcross-bar at its upper end having central spacing portions 8 and reducedend portions 9 yto which the upper ends of plates or supporting arms 10are pivotally held. The pair of plates or swinging supporting arms 10are pivotally' held at their lower ends at 11 Vto the floats 1 and 2adjacent ythe forward ends of the floats. y

A pair of oppositely disposed vertical posts or standards 12 arelrigidly held at their `lower ends to the floats 1 and 2 adjacent therear ends of said floats and a pair of upwardly extending arms 13 arehinged at their lowerends at 14 to the upper ends of the posts 12.Suitable braces 15 may be provided for assisting in supporting posts 12.

The arms 13 are pivotally held attheir upper ends to the reduced endportions 16 of a cross-bar having a central enlarged spacing portionl17. The cross-bar is formed integrally with or rigidly held to the upperend of a vertical rod or standard 18 which is rigidly secured at itslower end to the rear end of the bar 6. A pair of pulleys 19 arejournaled on vertical pivots in suitable supports 2O at the front andrear ends of bar 6. A pair of cables 21 pass over pulleys 19 and aresecuredat their ends to a pair of slides 22 held to guides 23 on thefloats vto move freely in an up and down direction. The pairs of arms 10and 13 are normally held in vertical positions and the floats normallymaintained directly opposite each other by a f flat spring 24, securedat one end tothe cross-bar 17 and at its other end to a pin 25 on one ofthe arms 13, `and a similar flat spring 26 held at one end to cross-bar9 and at its other end to a pin 27 on one of the arms 10. Y

An impelling device` is rigidly but adjustably heldto each of the arms13 to rock in unison with said arms. Each impeller comprises a bar 28,preferably rectangular in cross section, the upper end of which extendsthrough a rectangular aperture in a bracket 29 held to arm 13, and animpeller blade 31 pivotallyv held tothe lower end of the bar by abolt^32. The bars 28 are held in their adjusted positions by suitableset screws 30, and it will be obvious that the extent that bladesrl willdip into the water may beregulated by adjusting bars 28 vertically. Animpeller reversing device is provided for each of the impellers. Eachreversing device comprises a lever 33 pivotally held intermediate itsends at 37 to bar 28 and provided with a'pair of spaced stop lugs 34 and35 at its lower eud located at opposite sides of the impeller blade 3l.,A latch lever 36 pivotally held at one end to the upper end of lever isprovided with a pair of' spaced notches 58 and 39 adapted to co'peratewith a pin 40 on bar 28 to lock the reversing lever 33 in either of itstwo adjusted positions.

lfVhen lcversl are adjusted so that stops 34 will arrest the swingingmovement ofthe p blades lwhen the blades reach positions substantiallyparallel with bars 2S, the skater may move forwardly over the water bypushing' first one float and then the other forwardly. Il levers areadjusted so that stops will arrest the swinging movement of the bladeswhen the blades reach positions parallel with bars 28, `the skater maymove backwardly by pushing first one float and then ,the otherrearwardly. The device maybe steered by means of a rudder 4l'held to arotatable post 42 at the rear end of the float l. An arm 43 held to therudder post 42 is connected by a cable 44 with a rock Aarm 45 on avertical rock shaft 46 journaled in suitable bearings held to one of thestandards 5 and provided with an operating handle 47 preferably solocated as to .form practically a continuation of the adj acenthand-rail 4.

In the modified construction shown in Fig. 7, the various parts areconstructed and arranged as above described, except for the fact thatone of the cables 48, corresponding with the cables 21, extendsforwardly and the other rearwardly from the pulleys 19 and said cablesare connected at their ends with the floats adjacent the forward andrear ends of the floats by slides 49 and guides 50 similar to slides 22and guides 23. Referring to the construction shown in `Figs. S and 9,the bar 6 is connected at its ends by pairs of links 5l and 52 to pairsof rigid standards?) and 54 mounted on the floats. The impeller-bladecarrying bars 28 are adjustably held by set screws 55 in brackets 56formed on the lower ends of levers 57 pivotally held on studs 58 on thestandards 54. The levers 57 are provided with elongated slots 59 throughwhich pins 60 on the links 52 extend for vibrating the impellers.

In Figs. l0 and 1l a modified construction of impeller blade reversingmeans is shown.

This arrangement comprises a pair of stop bars 6l and 62 pivotally heldto the opposite ends of a pair of levers 63 and 64. The levers 63 and 64are pivotally held intermediate their ends to the impeller bladesupporting bar 28 and the lever 63 is formed with an extension or handleto permit either 'each float adjacent opposite ends of the float,

four links pivotally connected -at their upper ends `to the upper endsol' the standards and pivotally connected together in pairs at theirlower ends, a bar extending longitudinally of the floats and supportedby the pivotal connections between the lower ends of the pairs of links,two impeller-blade carriers pivotally held intermediatetheir ends tostandards adjacent the same endof differ- -ent floats, means forming apin and slot connection between the upper end ot each earrier and thelink connected with the standard supporting the carrier, and impellerblades mounted on the lower ends of the carriers.
